Inside the app

Eight surfaces, one obsession: getting you faster.

01 · Test

Type the way you read.

A clean, distraction-free test surface with a smooth, measured caret and per-character colouring. Train on the material you actually type — and bound every run exactly how you want.

• Train with known words, real quotes & source code (25 languages)
• Bound a run by time, word count or character limit
• Quote lengths short → thicc, plus custom text & adaptive drills
• alt+enter restart · ctrl+enter fresh text

02 · Feedback

A replay of every keystroke.

Finish a test and get the full picture — a detailed results graph plus a timeline replay you can scrub at up to 4×.

• WPM / raw / error timeline, fully charted
• Consistency, character breakdown & personal-best marker
• Timeline replay at 0.5× – 4× speed
• Repeat (enter), go fresh (ctrl+enter), or jump to analysis

03 · Progress

Watch the streak grow.

A bird's-eye view of your practice habit — the calendar that turns "I should practise" into "I practised today."

• Year-long activity calendar (contribution-graph style)
• Days active, current & longest streak, lifetime totals
• Month calendar with per-day best WPM
• Busiest day, most-typed source & per-session log

04 · Practice

Drill the keys, not your patience.

Structured lessons walk the board from the home row outward, with a live keyboard that highlights the very next key you need to hit.

• Lessons from home keys → reaches → full rows
• Live keyboard with next-key highlighting
• Problem-key panel ranks your weakest characters
• Set WPM & accuracy goals; toggle characters or words

05 · Code Lab · Browse

Type your own codebase.

Add any folder as a project and type the real source files inside it. The browser reads straight from disk and watches for changes as you work.

• Live recursive folder tree, updated as files change
• Junk & binaries hidden automatically
• Per-file line / word / character counts
• Folder paths persist; no file contents are ever stored

06 · Code Lab · Type

Real files, real indentation.

A large code pane handles whitespace the way an editor would, so the muscle memory you build is the muscle memory you actually use.

• Banners, licenses & ASCII-art stripped before you type
• Auto-indent and tab to indent
• Long files auto-pause after a 3s idle gap (excluded from WPM)
• ctrl+enter reloads the file

07 · Analysis

Find the keys holding you back.

Every keystroke updates per-character accuracy and latency. The analysis screen turns that into a map of exactly where to aim your next session.

• Keyboard accuracy heatmap across the whole board
• Weakest keys ranked by accuracy and reaction time
• Click keys to assemble a focused drill set
• WPM trend over your last 60 tests, plus coaching tips

08 · History

Every run, on the record.

A complete, local log of every test you've taken — searchable at a glance and visualised as one continuous speed curve.

• Full WPM trend with hover tooltips per test
• Tests · avg WPM · best WPM · avg accuracy · time typing
• Per-test source, speed, accuracy, errors & duration
• Stored in IndexedDB on your machine; clear it anytime
